Ruff practice for Sabres

‘”There have been areas of our game where we have tried to use video, and it has not reached some players,” Ruff said. “By going through an hour-and-a-half practice, with the number of games we have played, I may have done some damage. I will take that risk. We need to get better in two or three key areas — one is transition and one is just playing in our end. We have been flat-out sloppy.’
